# Portworx CSI Deployment Checklist
|
||||
|
||||
Pre-deployment checklist for Portworx CSI driver on Talos Linux with Pure Storage FlashArray.
|
||||
|
||||
## Phase 1: FlashArray Preparation
|
||||
|
||||
- [ ] **Create FlashArray storage admin user**
|
||||
- Username: `portworx-csi`
|
||||
- Role: Storage Admin
|
||||
- Password: Set in FlashArray UI
|
||||
|
||||
- [ ] **Generate FlashArray API token**
|
||||
- User: `portworx-csi`
|
||||
- Expiration: None (non-expiring)
|
||||
- Token format: `XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX`
|
||||
- **Save token immediately** (cannot be retrieved later)
|
||||
|
||||
- [ ] **Verify FlashArray management endpoint**
|
||||
- Test connectivity: `ping flasharray.mk-labs.cloud`
|
||||
- Test HTTPS: `curl -k https://flasharray.mk-labs.cloud`
|
||||
- Record IP/hostname: _______________________
|
||||
|
||||
- [ ] **Configure iSCSI targets on FlashArray**
|
||||
- Navigate to: **Settings → Network**
|
||||
- Verify iSCSI interfaces are enabled
|
||||
- Test discovery from Talos node:
|
||||
```bash
|
||||
talosctl -n <node> exec -- iscsiadm -m discovery -t st -p <flasharray-ip>
|
||||
```
|
||||
|
||||
- [ ] **(Optional) Enable FlashArray File Services for NFS**
|
||||
- Enable File Services: **Settings → File Services**
|
||||
- Create filesystem: `fastpass-nfs`
|
||||
- Create NFS policy with user mapping **disabled**
|
||||
- Record NFS endpoint: _______________________
|
||||
|
||||
## Phase 2: 1Password Secret Configuration
|
||||
|
||||
- [ ] **Create 1Password item**
|
||||
- Vault: `homelab`
|
||||
- Item name: `pure-flasharray-fastpass`
|
||||
- Category: Secure Note or API Credential
|
||||
|
||||
- [ ] **Add pure.json field to 1Password item**
|
||||
- Field name: `pure.json`
|
||||
- Field type: Text
|
||||
- Content format: JSON (see below)
|
||||
|
||||
- [ ] **Populate pure.json content**
|
||||
```json
|
||||
{
|
||||
"FlashArrays": [
|
||||
{
|
||||
"MgmtEndPoint": "flasharray.mk-labs.cloud",
|
||||
"APIToken": "paste-api-token-here",
|
||||
"NFSEndPoint": "flasharray-nfs.mk-labs.cloud"
|
||||
}
|
||||
]
|
||||
}
|
||||
```
|
||||
- Replace `flasharray.mk-labs.cloud` with actual endpoint
|
||||
- Replace `paste-api-token-here` with FlashArray API token
|
||||
- Remove `NFSEndPoint` line if not using File Services
|
||||
|
||||
- [ ] **Validate JSON syntax**
|
||||
```bash
|
||||
# Copy content from 1Password and validate
|
||||
echo '<paste-json>' | jq .
|
||||
```
|
||||
|
||||
- [ ] **Verify 1Password Connect can access item**
|
||||
```bash
|
||||
# From a pod with op CLI or via 1Password UI
|
||||
# Confirm item exists in homelab vault
|
||||
```
|
||||
|
||||
## Phase 3: Talos Node Configuration
|
||||
|
||||
- [ ] **Edit talconfig.yaml**
|
||||
- File: `~/git/homelab/talos/talhelper/talconfig.yaml`
|
||||
- Add patches from `cluster/platform/portworx-csi/talos-config-reference.yaml`
|
||||
- Sections to add:
|
||||
- [ ] System extensions (iscsi-tools, util-linux-tools)
|
||||
- [ ] Kernel modules (iscsi_tcp, dm_multipath, dm_round_robin)
|
||||
- [ ] /etc/multipath.conf file
|
||||
- [ ] /etc/udev/rules.d/99-pure-storage.rules file
|
||||
- [ ] kubelet extraMounts for /var/lib/iscsi
|
||||
|
||||
- [ ] **Generate updated Talos configs**
|
||||
```bash
|
||||
cd ~/git/homelab/talos/talhelper
|
||||
talhelper genconfig
|
||||
```
|
||||
|
||||
- [ ] **Apply Talos configuration to all worker nodes**
|
||||
```bash
|
||||
# For each worker node:
|
||||
talosctl apply-config \
|
||||
--file clusterconfig/<node-name>.yaml \
|
||||
--nodes <node-ip>
|
||||
```
|
||||
|
||||
Nodes:
|
||||
- [ ] Node 1: _________________ (IP: _____________)
|
||||
- [ ] Node 2: _________________ (IP: _____________)
|
||||
- [ ] Node 3: _________________ (IP: _____________)
|
||||
|
||||
- [ ] **Reboot all worker nodes**
|
||||
```bash
|
||||
# Reboot nodes one at a time to load kernel modules
|
||||
talosctl reboot --nodes <node-ip>
|
||||
|
||||
# Wait for node to come back online
|
||||
kubectl get nodes
|
||||
```
|
||||
|
||||
- [ ] **Verify iSCSI initiator on each node**
|
||||
```bash
|
||||
talosctl -n <node-ip> get service iscsid
|
||||
# Expected: iscsid service running
|
||||
```
|
||||
|
||||
- [ ] **Verify multipath on each node**
|
||||
```bash
|
||||
talosctl -n <node-ip> exec -- multipath -ll
|
||||
# Expected: multipath running (may show no paths yet)
|
||||
```
|
||||
|
||||
- [ ] **Verify unique iSCSI initiator names**
|
||||
```bash
|
||||
# For each node:
|
||||
talosctl -n <node-ip> read /etc/iscsi/initiatorname.iscsi
|
||||
|
||||
# Record initiator names (must be unique):
|
||||
# Node 1: iqn.1994-05.com.redhat:_______________
|
||||
# Node 2: iqn.1994-05.com.redhat:_______________
|
||||
# Node 3: iqn.1994-05.com.redhat:_______________
|
||||
```
|
||||
|
||||
- [ ] **Verify kernel modules loaded**
|
||||
```bash
|
||||
talosctl -n <node-ip> exec -- lsmod | grep -E "iscsi|dm_multipath"
|
||||
# Expected: iscsi_tcp, dm_multipath, dm_round_robin
|
||||
```
|
||||
|
||||
- [ ] **Test iSCSI discovery from each node**
|
||||
```bash
|
||||
talosctl -n <node-ip> exec -- \
|
||||
iscsiadm -m discovery -t st -p <flasharray-ip>
|
||||
# Expected: List of iSCSI targets from FlashArray
|
||||
```
|
||||
|
||||
## Phase 4: GitOps Deployment

# Node driver logs (on each node)
|
||||
kubectl logs -n portworx -l app=px-csi-node --tail=50
|
||||
```
|
||||
|
||||
## Phase 6: Functional Testing
|
||||
|
||||
- [ ] **Create test PVC with block storage**
|
||||
```bash

||||
storage: 1Gi
|
||||
EOF
|
||||
```
|
||||
|
||||
- [ ] **Verify PVC bound**
|
||||
```bash
|
||||
kubectl get pvc test-pure-block
|
||||
# Expected: STATUS=Bound
|
||||
```
|
||||
|
||||
- [ ] **Verify PV created on FlashArray**
|
||||
```bash
|
||||
kubectl get pv
|
||||
# Look for PV bound to test-pure-block
|
||||
|
||||
# Check FlashArray UI or API:
|
||||
# Volumes should show new volume created
|
||||
```
|
||||
|
||||
- [ ] **Create test pod using PVC**
|
||||
```bash
|
||||
cat <<EOF | kubectl apply -f -
|
||||
apiVersion: v1
|
||||
kind: Pod
|
||||
metadata:
|
||||
name: test-pure-block-pod
|
||||
namespace: default
|
||||
spec:
|
||||
containers:
|
||||
- name: test
|
||||
image: nginx:latest
|
||||
volumeMounts:
|
||||
- name: data
|
||||
mountPath: /data
|
||||
volumes:
|
||||
- name: data
|
||||
persistentVolumeClaim:
|
||||
claimName: test-pure-block
|
||||
EOF
|
||||
```
|
||||
|
||||
- [ ] **Verify pod is running**
|
||||
```bash
|
||||
kubectl get pod test-pure-block-pod
|
||||
# Expected: STATUS=Running
|
||||
```
|
||||
|
||||
- [ ] **Verify volume mounted in pod**
|
||||
```bash
|
||||
kubectl exec test-pure-block-pod -- df -h /data
|
||||
# Expected: Mount point shows 1Gi volume
|
||||
```
|
||||
|
||||
- [ ] **Test write to volume**
|
||||
```bash
|
||||
kubectl exec test-pure-block-pod -- \
|
||||
sh -c 'echo "test data" > /data/test.txt'
|
||||
|
||||
kubectl exec test-pure-block-pod -- cat /data/test.txt
|
||||
# Expected: "test data"
|
||||
```
|
||||
|
||||
- [ ] **Verify iSCSI session established**
|
||||
```bash
|
||||
# On node running test pod
|
||||
talosctl -n <node-ip> exec -- iscsiadm -m session
|
||||
# Expected: Active iSCSI session to FlashArray
|
||||
```
|
||||
|
||||
- [ ] **Clean up test resources**
|
||||
```bash
|
||||
kubectl delete pod test-pure-block-pod
|
||||
kubectl delete pvc test-pure-block
|
||||
```
|
||||
|
||||
- [ ] **(Optional) Test NFS file storage**
|
||||
- Repeat above steps with `storageClassName: pure-file`
|
||||
- Verify NFS export created on FlashArray
|
||||
|
||||
## Phase 7: Monitoring Setup
|
||||
|
||||
- [ ] **Verify Prometheus ServiceMonitor created**
|
||||
```bash
|
||||
kubectl get servicemonitor -n portworx
|
||||
```
|
||||
|
||||
- [ ] **Check Prometheus targets**
|
||||
- Navigate to Prometheus UI → Targets
|
||||
- Look for `portworx` or `px-csi` targets
|
||||
- Status should be UP
|
||||
|
||||
- [ ] **Query basic metrics**
|
||||
```promql
|
||||
# In Prometheus UI
|
||||
portworx_cluster_status
|
||||
portworx_volume_capacity_bytes
|
||||
```
|
||||
|
||||
- [ ] **(Optional) Create Grafana dashboard**
|
||||
- Import Portworx dashboard from Grafana.com
|
||||
- Or create custom dashboard
|
||||
|
||||
## Phase 8: Documentation & Handoff
|
||||
|
||||
- [ ] **Update homelab documentation**
|
||||
- Add FlashArray details to infrastructure docs
|
||||
- Document storage classes and use cases
|
||||
|
||||
- [ ] **Record credentials securely**
|
||||
- FlashArray management URL: ___________________
|
||||
- API token stored in: 1Password → homelab → pure-flasharray-fastpass
|
||||
- Portworx namespace: `portworx`
|
||||
|
||||
- [ ] **Create runbook for common tasks**
|
||||
- Volume expansion procedure
|
||||
- Snapshot creation/restore
|
||||
- Troubleshooting steps
|
||||
|
||||
- [ ] **Schedule follow-up review**
|
||||
- Date: _______________
|
||||
- Review metrics and performance
|
||||
- Adjust resource limits if needed
|
||||
|
||||
## Rollback Plan
|
||||
|
||||
If deployment fails, rollback procedure:
|
||||
|
||||
1. [ ] Delete ArgoCD application:
|
||||
```bash
|
||||
kubectl delete application -n argocd portworx-csi
|
||||
```
|
||||
|
||||
2. [ ] Delete namespace (if needed):
|
||||
```bash
|
||||
kubectl delete namespace portworx
|
||||
```
|
||||
|
||||
3. [ ] Delete StorageClasses:
|
||||
```bash
|
||||
kubectl delete storageclass pure-block pure-file
|
||||
```
|
||||
|
||||
4. [ ] Delete CRDs (if needed):
|
||||
```bash
|
||||
kubectl delete crd storageclusters.core.libopenstorage.org
|
||||
```
|
||||
|
||||
5. [ ] Revert Talos configuration (if needed):
|
||||
```bash
|
||||
# Remove portworx-csi patches from talconfig.yaml
|
||||
talhelper genconfig
|
||||
talosctl apply-config --file clusterconfig/<node>.yaml --nodes <node-ip>
|
||||
```
|
||||
|
||||
## Success Criteria
|
||||
|
||||
Deployment is successful when:
|
||||
|
||||
- [ ] All pods in `portworx` namespace are Running

|
||||
|
||||
## Next Steps
|
||||
|
||||
### 1. Before Deployment
|
||||
- [ ] Create FlashArray storage admin user and API token
|
||||
- [ ] Add FlashArray credentials to 1Password
|
||||
- [ ] Apply Talos configuration to all worker nodes:
|
||||
```bash
|
||||
cd ~/git/homelab/talos/talhelper
|
||||
# Add portworx-csi patches to talconfig.yaml
|
||||
talhelper genconfig
|
||||
talosctl apply-config --file clusterconfig/<node>.yaml --nodes <node-ip>
|
||||
talosctl reboot --nodes <node-ip>
|
||||
```
|
||||
- [ ] Verify iSCSI and multipath on each node
|
||||
- [ ] Run validation script: `./validate-prereqs.sh`
|
||||
|
||||
### 2. Deploy
|
||||
```bash
|
||||
cd ~/git/homelab
|
||||
git add cluster/platform/portworx-csi/
|
||||
git commit -m "Add Portworx CSI driver for Pure FlashArray"
|
||||
git push origin main
|
||||
|
||||
# ArgoCD will auto-sync (wave 2)
|
||||
# Or manually sync:
|
||||
argocd app sync portworx-csi
|
||||
```
|
||||
|
||||
### 3. Verify Deployment
|
||||
```bash
|
||||
# Check ArgoCD application
|
||||
kubectl get application -n argocd portworx-csi
|
||||
|
||||
# Verify pods
|
||||
kubectl get pods -n portworx
|
||||
|
||||
# Check StorageCluster
|
||||
kubectl get storagecluster -n portworx
|
||||
|
||||
# Test with sample PVC (see DEPLOYMENT-CHECKLIST.md Phase 6)
|
||||
```
|
||||
|
||||
### 4. Post-Deployment
|
||||
- [ ] Configure Prometheus/Grafana dashboards for Portworx metrics
|
||||
- [ ] Update homelab infrastructure documentation
|
||||
- [ ] Create runbook for common operations
|
||||
- [ ] Schedule follow-up review after 1 week
|
||||
|
||||
## Key Design Decisions
|
||||
|
||||
### Why Portworx CSI?
|
||||
- **Direct Access**: FlashArray volumes directly attached to pods (no aggregation layer)
|
||||
- **Native Integration**: Official Pure Storage support
|
||||
- **Feature Rich**: Snapshots, expansion, topology-aware provisioning
|
||||
- **Talos Compatible**: Works with Talos Linux after proper configuration
|
||||
|
||||
### Why iSCSI (vs NVMe-oF)?
|
||||
- **Broad Compatibility**: Works on all Talos nodes without special NICs
|
||||
- **Proven**: Mature protocol with extensive documentation
|
||||
- **Upgrade Path**: Can migrate to NVMe-oF later for performance
|
||||
- **Simpler Setup**: Fewer hardware dependencies
|
||||
|
||||
### Why Multi-Source ArgoCD Application?
|
||||
- **Consistency**: Follows homelab pattern (same as cert-manager, nfs-csi)
|
||||
- **Upstream Helm**: Use official Portworx chart, not custom forks
|
||||
- **Local Overrides**: StorageClasses and configs in Git
|
||||
- **GitOps Friendly**: All configuration is declarative
|
||||
|
||||
### Why Wave 2?
|
||||
- **Dependencies**: Needs External Secrets (wave 1) for credentials
|
||||
- **Before Apps**: Storage must be ready before applications deploy
|
||||
- **Parallel Safe**: Can deploy alongside other platform services
|
||||
|
||||
## Validation Results
|
||||
|
||||
All YAML files validated successfully:
|
||||
- ✅ `application.yaml` - Valid YAML
|
||||
- ✅ `externalsecret.yaml` - Valid YAML
|
||||
- ✅ `operator-values.yaml` - Valid YAML
|
||||
- ✅ `storageclass-block.yaml` - Valid YAML
|
||||
- ✅ `storageclass-file.yaml` - Valid YAML
|
||||
- ✅ `storagecluster.yaml` - Valid YAML
|
||||
- ✅ `talos-config-reference.yaml` - Valid YAML
|
||||
|
||||
## Important Notes
|
||||
|
||||
### Talos Configuration
|
||||
⚠️ **CRITICAL**: The `talos-config-reference.yaml` file is **NOT** a Kubernetes resource. It documents the required Talos patches that must be applied via `talhelper` or `talosctl`. Do not attempt to `kubectl apply` this file.
|
||||
|
||||
### Secret Management
|
||||
The FlashArray API token is stored in 1Password and synced to Kubernetes via External Secrets Operator. Never commit credentials to Git.
|
||||
|
||||
### Node Reboots Required
|
||||
After applying Talos configuration with kernel modules, nodes **must be rebooted** for modules to load. Schedule appropriately.
|
||||
|
||||
### iSCSI Initiator Names
|
||||
Each Talos node must have a **unique** iSCSI initiator name. Verify uniqueness across all nodes to avoid conflicts.
|
||||
|
||||
### Default StorageClass
|
||||
Neither `pure-block` nor `pure-file` is set as the default StorageClass. The existing `nfs-emporium` remains the default. Applications must explicitly request Pure storage by specifying `storageClassName`.
|
||||
|
||||
## Support and References
|
||||
|
||||
### Documentation
|
||||
- **Full Deployment Guide**: `cluster/platform/portworx-csi/README.md`
|
||||
- **Deployment Checklist**: `cluster/platform/portworx-csi/DEPLOYMENT-CHECKLIST.md`
|
||||
- **Quick Reference**: `cluster/platform/portworx-csi/QUICKREF.md`
|
||||
|
||||

|
||||
- [Talos Storage Guide](https://www.talos.dev/latest/kubernetes-guides/configuration/storage/)
|
||||
|
||||
### Troubleshooting
|
||||
If issues arise during deployment:
|
||||
1. Check `DEPLOYMENT-CHECKLIST.md` for step-by-step verification
|
||||
2. Review `QUICKREF.md` for troubleshooting commands
|
||||
3. Run `validate-prereqs.sh` to check prerequisites
|
||||
4. Consult Portworx CSI documentation for advanced scenarios
|
||||
|
||||

# Portworx Operator
|
||||
kubectl logs -n portworx -l app=portworx-operator --tail=100
|
||||
|
||||
# PX-CSI Controller
|
||||
kubectl logs -n portworx -l app=px-csi-controller --tail=100
|
||||
|
||||
# PX-CSI Node driver (specific node)
|
||||
kubectl logs -n portworx -l app=px-csi-node --tail=100
|
||||
|
||||
# Follow logs in real-time
|
||||
kubectl logs -n portworx -l app=px-csi-controller -f
|
||||
```
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### Check iSCSI on Talos Nodes
|
||||
```bash
|
||||
# List iSCSI sessions
|
||||
talosctl -n <node-ip> exec -- iscsiadm -m session
|
||||
|
||||
# Discover FlashArray targets
|
||||
talosctl -n <node-ip> exec -- iscsiadm -m discovery -t st -p <flasharray-ip>
|
||||
|
||||
# Check initiator name (must be unique)
|
||||
talosctl -n <node-ip> read /etc/iscsi/initiatorname.iscsi
|
||||
```
|
||||
|
||||
### Check Multipath
|
||||
```bash
|
||||
# Multipath status
|
||||
talosctl -n <node-ip> exec -- multipath -ll
|
||||
|
||||
# Reload multipath config
|
||||
talosctl -n <node-ip> exec -- systemctl reload multipathd
|
||||
|
||||
# Multipath devices
|
||||
talosctl -n <node-ip> exec -- ls -l /dev/mapper/
|
||||
```
|
||||
|
||||
### Verify FlashArray Connectivity
|
||||
```bash
|
||||
# From PX-CSI pod
|
||||
kubectl exec -n portworx -it <px-pod> -- ping <flasharray-ip>
|
||||
|
||||
# Test API endpoint
|
||||
kubectl exec -n portworx -it <px-pod> -- \
|
||||
curl -k https://<flasharray-mgmt-ip>/api/2.0/arrays
|
||||
```
|
||||
|
||||
### Check Secret
|
||||
```bash
|
||||
# Verify secret exists
|
||||
kubectl get secret -n portworx px-pure-secret
|
||||
|
||||
# View secret content (pure.json)
|
||||
kubectl get secret -n portworx px-pure-secret \
|
||||
-o jsonpath='{.data.pure\.json}' | base64 -d | jq .
|
||||
|
||||
# Check ExternalSecret status
|
||||
kubectl get externalsecret -n portworx px-pure-secret
|
||||
kubectl describe externalsecret -n portworx px-pure-secret
|
||||
```
|
||||
|
||||
### Volume Not Attaching
|
||||
```bash
|
||||
# Check PVC events
|
||||
kubectl describe pvc <pvc-name>
|
||||
|
||||
# Check pod events
|
||||
kubectl describe pod <pod-name>
|
||||
|
||||
# Check PV
|
||||
kubectl get pv
|
||||
kubectl describe pv <pv-name>
|
||||
|
||||
# Check volume attachment
|
||||
kubectl get volumeattachment
|
||||
```
|
||||
|
||||
### Pod Stuck in ContainerCreating
|
||||
```bash
|
||||
# Check events
|
||||
kubectl describe pod <pod-name>
|
||||
|
||||
# Check PVC status
|
||||
kubectl get pvc -n <namespace>
|
||||
|
||||
# Check node where pod is scheduled
|
||||
POD_NODE=$(kubectl get pod <pod-name> -o jsonpath='{.spec.nodeName}')
|
||||
echo "Pod scheduled on: $POD_NODE"
|
||||
|
||||
# Check iSCSI on that node
|
||||
talosctl -n $POD_NODE exec -- iscsiadm -m session
|
||||
```
|
||||
|
||||
## Monitoring
|
||||
|
||||
### Prometheus Queries
|
||||
```promql
|
||||
# Cluster status
|
||||
portworx_cluster_status
|
||||
|
||||
# Volume capacity
|
||||
portworx_volume_capacity_bytes
|
||||
|
||||
# Volume usage
|
||||
portworx_volume_usage_bytes
|
||||
|
||||
# I/O metrics
|
||||
rate(portworx_volume_read_bytes[5m])
|
||||
rate(portworx_volume_write_bytes[5m])
|
||||
```
|
||||
|
||||
### List All PVCs Using Pure Storage
|
||||
```bash
|
||||
# Block storage
|
||||
kubectl get pvc --all-namespaces -o json | \
|
||||
jq -r '.items[] | select(.spec.storageClassName == "pure-block") |
|
||||
"\(.metadata.namespace)/\(.metadata.name) - \(.status.phase)"'
|
||||
|
||||
# File storage
|
||||
kubectl get pvc --all-namespaces -o json | \
|
||||
jq -r '.items[] | select(.spec.storageClassName == "pure-file") |
|
||||
"\(.metadata.namespace)/\(.metadata.name) - \(.status.phase)"'
|
||||
```
|
||||
|
||||
### Storage Usage by Namespace
|
||||
```bash
|
||||
kubectl get pvc --all-namespaces -o json | \
|
||||
jq -r '.items[] | select(.spec.storageClassName | startswith("pure-")) |
|
||||
"\(.metadata.namespace)\t\(.spec.resources.requests.storage)"' | \
|
||||
awk '{arr[$1]+=$2} END {for (i in arr) print i, arr[i]}'

# Portworx CSI Driver for Pure Storage FlashArray
|
||||
|
||||
GitOps deployment of Portworx CSI driver for Pure Storage FlashArray on Talos Linux in the `fastpass` Kubernetes cluster.
|
||||
|
||||
## Overview
|
||||
|
||||
Portworx CSI enables Kubernetes to provision and manage storage directly from Pure Storage FlashArray, providing:
|
||||
|
||||
- **Block Storage**: High-performance iSCSI volumes for databases and stateful apps
|
||||
- **File Storage**: NFS-based shared storage from FlashArray File Services
|
||||
- **Dynamic Provisioning**: Automatic volume creation via StorageClasses
|
||||
- **Volume Snapshots**: CSI snapshots for backup and restore
|
||||
- **Volume Expansion**: Online volume resizing without downtime
|
||||
|
||||

## Prerequisites
|
||||
|
||||
### 1. FlashArray Configuration
|
||||
|
||||
#### Create FlashArray User and API Token
|
||||
|
||||
1. **Create a storage admin user:**
|
||||
- Navigate to FlashArray dashboard → **Settings** → **Access** → **Users**
|
||||
- Click **Create User**
|
||||
- Set role to **Storage Admin**
|
||||
- Username: `portworx-csi`
|
||||
|
||||
2. **Generate API token:**
|
||||
- Select the user → **Create API Token**
|
||||
- Leave **Expires in** blank for non-expiring token
|
||||
- Copy the token immediately
|
||||
|
||||
#### Configure FlashArray for Block Storage (iSCSI)
|
||||
|
||||
1. **Verify iSCSI targets are configured:**
|
||||
```bash
|
||||
# From any Talos node
|
||||
iscsiadm -m discovery -t st -p <flasharray-mgmt-ip>
|
||||
```
|
||||
|
||||
2. **Enable FlashArray network interfaces for iSCSI**
|
||||
|
||||
#### Configure FlashArray File Services (Optional - for NFS)
|
||||
|
||||
If using FlashArray File Services:
|
||||
|
||||
1. **Enable File Services** on FlashArray
|
||||
2. **Create a filesystem** for Kubernetes volumes
|
||||
3. **Create an NFS policy** with user mapping disabled:
|
||||
- Edit `nfs-simple` policy or create new policy
|
||||
- Disable user mapping to avoid UID/GID issues
|
||||
- Set `no_root_squash` if needed
|
||||
|
||||
### 2. 1Password Secret Setup
|
||||
|
||||
Create a 1Password item with FlashArray credentials:
|
||||
|
||||
**Vault:** `homelab`
|
||||
**Item Name:** `pure-flasharray-fastpass`
|
||||
**Field Name:** `pure.json`
|
||||
**Field Type:** Text
|
||||
**Field Value:**
|
||||
```json
|
||||
{
|
||||
"FlashArrays": [
|
||||
{
|
||||
"MgmtEndPoint": "flasharray.mk-labs.cloud",
|
||||
"APIToken": "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx",
|
||||
"NFSEndPoint": "flasharray-nfs.mk-labs.cloud"
|
||||
}
|
||||
]
|
||||
}
|
||||
```
|
||||
|
||||
**Notes:**
|
||||
- Replace `flasharray.mk-labs.cloud` with your FlashArray management endpoint
|
||||
- Replace the API token with the actual token from FlashArray
|
||||
- Include `NFSEndPoint` only if using FlashArray File Services
|
||||
- For IPv6, enclose IP in brackets: `"[2001:db8::1]"`
|
||||
|
||||
### 3. Talos Node Configuration
|
||||
|
||||
Apply the following patches to **all worker nodes** in `talos/talhelper/talconfig.yaml`:
|
||||
|
||||
```yaml
|
||||
nodes:
|
||||
# Add to each worker node definition
|
||||
patches:
|
||||

extraMounts:
|
||||
- destination: /var/lib/iscsi
|
||||
type: bind
|
||||
source: /var/lib/iscsi
|
||||
options:
|
||||
- bind
|
||||
- rshared
|
||||
- rw
|
||||
```
|
||||
|
||||
**Apply Talos configuration:**
|
||||
```bash
|
||||
# From city-hall (talhelper host)
|
||||
cd ~/git/homelab/talos/talhelper
|
||||
talhelper genconfig
|
||||
talosctl apply-config --file clusterconfig/<node>.yaml --nodes <node-ip>
|
||||
|
||||
# Reboot nodes to load kernel modules
|
||||
talosctl reboot --nodes <node-ip>
|
||||
```
|
||||
|
||||
### 4. Verify Talos Prerequisites
|
||||
|
||||
After applying Talos configuration and rebooting:
|
||||
|
||||
```bash
|
||||
# Check iSCSI initiator service
|
||||
talosctl -n <node-ip> get service iscsid
|
||||
|
||||
# Verify multipath is running
|
||||
talosctl -n <node-ip> exec -- multipath -ll
|
||||
|
||||
# Check initiator name (must be unique per node)
|
||||
talosctl -n <node-ip> read /etc/iscsi/initiatorname.iscsi
|
||||
|
||||
# Verify kernel modules loaded
|
||||
talosctl -n <node-ip> exec -- lsmod | grep -E "iscsi|dm_multipath"
|
||||
|
||||
# Test iSCSI discovery
|
||||
talosctl -n <node-ip> exec -- iscsiadm -m discovery -t st -p <flasharray-ip>
|
||||
```
|
||||
|
||||
## Deployment
|
||||
|
||||
### 1. Commit and Push to Git
|
||||
|
||||
```bash
|
||||
cd ~/git/homelab
|
||||
git add cluster/platform/portworx-csi/
|
||||
git commit -m "Add Portworx CSI driver for Pure FlashArray"
|
||||
git push origin main
|
||||
```
|
||||
|
||||
### 2. Deploy via ArgoCD
|
||||
|
||||
The application is configured with `sync-wave: 2`, so it will deploy after External Secrets Operator and 1Password Connect.
|
||||
|
||||
**Option A: Auto-sync (recommended)**
|
||||
```bash
|
||||
# ArgoCD will automatically sync after detecting changes
|
||||
# Check status:
|
||||
kubectl get application -n argocd portworx-csi
|
||||
```
|
||||
|
||||
**Option B: Manual sync**
|
||||
```bash
|
||||
# Sync via CLI
|
||||
argocd app sync portworx-csi
|
||||
|
||||
# Or sync via UI
|
||||
# Navigate to ArgoCD UI → Applications → portworx-csi → Sync
|
||||
```
|
||||
|
||||
### 3. Verify Deployment
|
||||
|
||||
```bash
|
||||
# Check ArgoCD application status
|
||||
kubectl get application -n argocd portworx-csi
|
||||
|
||||
# Check Portworx Operator
|
||||
kubectl get deployment -n portworx portworx-operator
|
||||
kubectl get pods -n portworx -l app=portworx-operator
|
||||
|
||||
# Check StorageCluster status
|
||||
kubectl get storagecluster -n portworx px-cluster-fastpass
|
||||
kubectl describe storagecluster -n portworx px-cluster-fastpass
|
||||
|
||||
# Check PX-CSI pods
|
||||
kubectl get pods -n portworx
|
||||
|
||||
# Verify secret was created from 1Password
|
||||
kubectl get secret -n portworx px-pure-secret
|
||||
kubectl get secret -n portworx px-pure-secret -o jsonpath='{.data.pure\.json}' | base64 -d | jq
|
||||
|
||||
# Check CSI driver registration
|
||||
kubectl get csidrivers
|
||||
kubectl get csinode
|
||||
|
||||
# Verify StorageClasses
|
||||
kubectl get storageclass pure-block pure-file
|
||||
```
|
||||
|
||||
Expected output:
|
||||
```
|
||||
NAME PROVISIONER RECLAIMPOLICY VOLUMEBINDINGMODE ALLOWVOLUMEEXPANSION
|
||||
pure-block pxd.portworx.com Delete Immediate true
|
||||
pure-file pxd.portworx.com Delete Immediate true
|
||||
```
|
||||
|
||||
## Usage
|
||||
|
||||
### Create a PVC with Block Storage
|
||||
|
||||
```yaml
|
||||
apiVersion: v1
|
||||
kind: PersistentVolumeClaim
|
||||
metadata:
|
||||
name: postgres-data
|
||||
namespace: default
|
||||
spec:
|
||||
accessModes:
|
||||
- ReadWriteOnce
|
||||
storageClassName: pure-block
|
||||
resources:
|
||||
requests:
|
||||
storage: 10Gi
|
||||
```
|
||||
|
||||
### Create a PVC with File Storage (NFS)
|
||||
|
||||
```yaml
|
||||
apiVersion: v1
|
||||
kind: PersistentVolumeClaim
|
||||
metadata:
|
||||
name: shared-data
|
||||
namespace: default
|
||||
spec:
|
||||
accessModes:
|
||||
- ReadWriteMany
|
||||
storageClassName: pure-file
|
||||
resources:
|
||||
requests:
|
||||
storage: 50Gi
|
||||
```
|
||||
|
||||
### Volume Expansion
|
||||
|
||||
```bash
|
||||
# Edit PVC to increase size
|
||||
kubectl patch pvc postgres-data -p '{"spec":{"resources":{"requests":{"storage":"20Gi"}}}}'
|
||||
|
||||
# Verify expansion
|
||||
kubectl get pvc postgres-data
|
||||
```
|
||||
|
||||
### Volume Snapshots
|
||||
|
||||
```yaml
|
||||
apiVersion: snapshot.storage.k8s.io/v1
|
||||
kind: VolumeSnapshot
|
||||
metadata:
|
||||
name: postgres-backup
|
||||
namespace: default
|
||||
spec:
|
||||
volumeSnapshotClassName: px-csi-snapshot-class
|
||||
source:
|
||||
persistentVolumeClaimName: postgres-data
|
||||
```
|
||||
|
||||
## StorageClasses
|
||||
|
||||
### pure-block
|
||||
- **Backend:** Pure Storage FlashArray (iSCSI)
|
||||
- **Access Mode:** ReadWriteOnce (RWO)
|
||||
- **Use Case:** Databases, stateful applications requiring block storage
|
||||
- **Features:** High performance, low latency, volume expansion
|
||||
- **Filesystem:** ext4
|
||||
|
||||
### pure-file
|
||||
- **Backend:** Pure Storage FlashArray File Services (NFS)
|
||||
- **Access Mode:** ReadWriteMany (RWX)
|
||||
- **Use Case:** Shared storage for multi-pod applications
|
||||
- **Features:** NFS v4.1, concurrent access, volume expansion
|
||||
- **Mount Options:** hard, timeo=600, retrans=3
|
||||
|
||||
## Monitoring
|
||||
|
||||
Portworx CSI exposes Prometheus metrics:
|
||||
|
||||
```bash
|
||||
# Check ServiceMonitor (if Prometheus Operator is installed)
|
||||
kubectl get servicemonitor -n portworx
|
||||
|
||||
# View metrics endpoint
|
||||
kubectl get svc -n portworx -l app=portworx-api
|
||||
|
||||
# Example metrics:
|
||||
# - portworx_volume_usage_bytes
|
||||
# - portworx_volume_capacity_bytes
|
||||
# - portworx_cluster_status
|
||||
```
|
||||
|
||||
To enable Prometheus scraping, the `kube-prometheus-stack` will auto-discover the ServiceMonitor.
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### Pods stuck in ContainerCreating
|
||||
|
||||
```bash
|
||||
# Check PVC status
|
||||
kubectl get pvc
|
||||
kubectl describe pvc <pvc-name>
|
||||
|
||||
# Check PV binding
|
||||
kubectl get pv
|
||||
|
||||
# Check PX-CSI node driver logs
|
||||
kubectl logs -n portworx -l app=px-csi-driver --tail=100
|
||||
|
||||
# Check iSCSI sessions on node
|
||||
talosctl -n <node-ip> exec -- iscsiadm -m session
|
||||
```
|
||||
|
||||
### Volume not attaching
|
||||
|
||||
```bash
|
||||
# Check StorageCluster status
|
||||
kubectl get storagecluster -n portworx -o yaml
|
||||
|
||||
# Check PX-CSI controller logs
|
||||
kubectl logs -n portworx -l app=portworx-operator
|
||||
|
||||
# Verify FlashArray connectivity
|
||||
kubectl exec -n portworx -it <px-pod> -- ping <flasharray-mgmt-ip>
|
||||
|
||||
# Check secret is valid
|
||||
kubectl get secret -n portworx px-pure-secret -o yaml
|
||||
```
|
||||
|
||||
### Multipath issues
|
||||
|
||||
```bash
|
||||
# Check multipath status on node
|
||||
talosctl -n <node-ip> exec -- multipath -ll
|
||||
|
||||
# Restart multipathd if needed
|
||||
talosctl -n <node-ip> exec -- systemctl restart multipathd
|
||||
|
||||
# Verify udev rules applied
|
||||
talosctl -n <node-ip> exec -- udevadm control --reload-rules
|
||||
talosctl -n <node-ip> exec -- udevadm trigger
|
||||
```
|
||||
|
||||
### FlashArray API errors
|
||||
|
||||
```bash
|
||||
# Verify API token is valid
|
||||
# From a pod with curl:
|
||||
curl -k -H "api-token: <token>" https://<flasharray-mgmt-ip>/api/2.0/arrays
|
||||
|
||||
# Check PX-CSI can reach FlashArray
|
||||
kubectl exec -n portworx -it <px-pod> -- curl -k https://<flasharray-mgmt-ip>
|
||||
```
|
||||
|
||||
## Rollback
|
||||
|
||||
If deployment fails:
|
||||
|
||||
```bash
|
||||
# Delete ArgoCD application (keeps namespace and CRDs)
|
||||
kubectl delete application -n argocd portworx-csi
|
||||
|
||||
# Or remove via ArgoCD UI
|
||||
|
||||
# Full cleanup (if needed):
|
||||
kubectl delete namespace portworx
|
||||
kubectl delete crd storageclusters.core.libopenstorage.org
|
||||
kubectl delete storageclass pure-block pure-file
|
||||
```

## Architecture Decisions
|
||||
|
||||
- **Sync Wave 2:** Deployed after External Secrets Operator (wave 1) but before applications
|
||||
- **iSCSI Protocol:** Selected for broad compatibility; NVMe-oF can be added later
|
||||
- **No Default StorageClass:** Keeps existing `nfs-emporium` as default; apps opt-in to Pure
|
||||
- **Telemetry Disabled:** For homelab privacy; can enable for production support
|
||||
- **Single FlashArray:** Configuration supports multiple arrays; add to `pure.json` as needed
|
||||
|
||||
## Future Enhancements
|
||||
|
||||
- [ ] Enable CSI topology for multi-zone deployments
|
||||
- [ ] Configure NVMe-oF protocol for lower latency
|
||||
- [ ] Set up FlashArray ActiveCluster for HA
|
||||
- [ ] Enable Portworx Fusion Controller
|
||||
- [ ] Configure VLAN binding for isolated storage traffic
|
||||
- [ ] Implement backup/restore workflows with snapshots
|
||||
- [ ] Add Grafana dashboards for Portworx metrics
